2019 Map of Iditarod D-5 NW

About this map

Big Yetna River dominates this interior Alaskan landscape, winding through a complex network of wetlands and oxbow lakes. The 2019 survey documents a terrain defined by shifting watercourses and seasonal saturation, where the river's meandering path across the Yukon-Koyukuk region creates a labyrinth of small ponds and unnamed tributaries. This document is primarily a record of the natural hydrology and the public land survey system grid, including townships like t34n r48w and t33n r49w. The absence of named settlements or roads reflects the isolation of this portion of the Alaskan interior, providing researchers a base map of the untouched riparian environment as it existed in the early twenty-first century.
